4d9be96a81 Changed output format of libmpcdec to non-interleaved stereo for a slight speed boost. Also stopped wasting 10kb of IRAM in the output sample buffer.

c8193b8da5 The seek_time member of the codec API needs to be decremented before use as a seeking time.

741012004b Disabled Musepack seeking, since it's so slow that most users conclude the codec has crashed. Left in original seek code for those who're aware of the issue and want seek support.

fca6b63ef7 Fix bug with FLAC and ALAC output being half the correct volume. The DSP_SET_SAMPLE_DEPTH function expects needs clarifying or changing - it seems to expect one less than the number of bits in cases where the depth is greater than the native depth (16 bits).

dff9352430 Initial seeking support. This only seeks to the nearest point (before the target sample) in the seektable. NOTE: not all FLAC files have seektables - some front-ends have the skill to create FLAC files without them. You can add seek points every 10 seconds to a FLAC file with the command: metaflac --add-seekpoint=10s file.flac

f1844c4166 1) Always enable the DSP. 2) Change codec to output one 32-bit array per channel containing samples left-shifted to 28-bits (instead of 16-bit interleaved samples). 3) Remove the two 16KB internal predicterror_buffer arrays (we use the output arrays instead) 4) Small internal rearrangement of the code.
